Description
Purpose: This study examined differences in the hamstring-to-quadriceps strength ratio (H:Q) between dominant and non-dominant legs in collegiate women soccer athletes. Methods: Eleven NCAA Division I female soccer players participated; one was excluded due to equipment malfunction. Following a standardized warm-up, athletes completed unilateral isokinetic knee extension and flexion on an isokinetic dynamometer at 60°/s, 180°/s, and 300°/s. For each leg and velocity, athletes performed three submaximal trials followed by five maximal effort repetitions, with 60 seconds of rest between velocities. A two-way repeated measures ANOVA was conducted to assess differences in H:Q ratios between the limbs across velocities. Results: No significant (p>0.05) interaction was observed between the legs across velocities for hamstring or quadricep strength. Strength was significantly (p< 0.05) decreased as speed increased. A significant interaction was observed for H:Q, with the dominant leg displaying a significantly higher H:Q. Additionally, the H:Q increased significantly from 60°/s to 180°/s, with no further significant change at 300°/s. The dominant leg showed a tread (p=0.06) toward higher H:Q at 60°/s and was significantly greater at 300°/s. Conclusion: The athletes displayed a greater H:Q in the dominant leg, suggesting the non-dominant leg requires targeted training, particularly at higher movement velocities.
